- Scientists at Northwestern University have developed a groundbreaking single-injection therapy using "dancing molecules" to potentially reverse paralysis and repair tissue in severe spinal cord injuries. Just 4 weeks post-treatment, mice regained walking ability, heralding a new era in regenerative medicine.
The therapy sends biological signals to activate repair and regeneration cells, significantly improving spinal cord injuries by:
+ Regenerating severed neuronal axons;
+ Substantially reducing scar tissue that impedes regeneration;
+ Rebuilding myelin around neurons for efficient signal transmission;
+ Forming functional blood vessels for nutrient delivery;
+ Enhancing the survival of more motor neurons.
Materials used in the therapy degrade into nutrients within 12 weeks, disappearing without notable side effects, marking a first in controlling molecule movement for enhanced treatment efficacy.
According to Samuel I. Stupp, the study lead, this research aims to provide therapy to individuals paralyzed due to injury or disease, a challenge for decades due to the central nervous system's minimal regenerative capability. With nearly 300,000 Americans living with spinal cord injuries, facing immense life challenges and a significantly reduced life expectancy, this novel approach could vastly improve patient outcomes.
The therapy works by adjusting the movement of molecules, enabling them to accurately engage with constantly moving cell receptors. Injected as a liquid, it instantly forms a complex network of nanofibers mimicking the spinal cord's extracellular matrix. This synthetic material communicates with cells by matching natural molecular movement and combining signals for receptors, pioneering a new method to target intermediary neurons causing pain.
A breakthrough in the study is the control of over 100,000 molecules' collective motion within nanofibers, allowing them to connect more effectively with receptors. After binding, the moving molecules activate dual signals crucial for spinal cord repair: one encourages the regeneration of neurons' long tails, or axons, critical for communication between the brain and body; the other ensures neuron survival post-injury by promoting the growth of lost blood vessels and reducing nerve scarring, acting as a physical barrier to healing.
Mimicking essential natural proteins needed for the desired biological reactions, this therapy could offer a less expensive, longer-lasting solution to current treatments, significantly impacting spinal cord injury outcomes and potentially addressing neurodegenerative diseases and stroke strategies.
